A Stitch in Time: Masonry Repair Kits

There are a number of reasons that masonry can become cracked but, whatever the reason, such cracks must be quickly and profes­si­onally repaired. The Crack Stitching Kit from Twistfix is designed to offer a complete, lasting solution to cracks in brick, block and stone walls, delivering consistently professional results. And, when you take into account our signature low prices, this kit represents incredible value for money.

At the centre of the Twistfix Crack Stitching Kit are helical crack stitching bars, each of which is manufactured from 304 grade stainless steel to ensure the perfect combination of strength and corrosion-resistance. Every high-tensile helical bar is precision-profiled. ensuring perfect results when bonded into pre-cut horizontal slots in the bed joints. Structural integrity is restored as the cracks are firmly stitched together.

Any building can suffer from cracks in masonry but the issue is more common in older properties. Crack stitching bars make a perfect retrofit solution in such cases, creating minimal disruption during the installation process. Aesthetic appeal is preserved as both bars and grout are completely invisible once installed.

As well as helical bars, the Twistfix Crack Stitching kit contains specially-formulated WHO-60 masonry repair grout, into which the bars are embedded. The grout is easily mixed and subsequently applied using a helix mixer paddle, brick jointer, Grout-Master applicator and Hi-Flo nozzle; these components are supplied within the kit.

Lateral Restraint Ties for Structural Integrity

Our last article featured our helical structural repair ties, which are used to secure brick ​façades to perpendicular walls, helping to restore structural integrity. These crucial components go hand-in-hand with lateral restraint ties, which are used horizontally to tie façades to a buildings flooring diaphragm; together they provide a comprehensive structural solution to stabilise bowing walls.

Tying bulging brickwork to the internal structure of a floor is made quick, simple and effective with lateral restraint ties from Twistfix. Each robust, high-quality tie features a drill-like leading end, designed to powerfully cut into softwood using a standard drill. The bars are simply wound into the timber before being resin-fixes to the gable brickwork, delivering an immediate, lasting solution.

One of the most impressive features of lateral restraint bars is that they are fixed from outside of the property, meaning that a minimum of disruption occurs during installation. Determining the position of the relevant joists and ensuring services such as gas, water and electricity are avoided simply involves lifting a small number of floorboards before installation proceeds.

Lateral restraint tie bars are supplied in packs of five and there is a choice of different lengths available to suit any application. An even more economical option is the comprehensive Lateral Restraint Wall Tie Kit, which contains everything required to complete a professional job. The kit includes:

  • Five lateral restraint tie bars, each of one metre in length
  • An SDS setting tool to allow easy winding of restraint ties into joists
  • An SDS masonry drill bit
  • A pack of polyester resin with integral mixer nozzle
  • A co-axial resin applicator

The Solution to Bowing Walls

By necessity, the walls of a property are generally slender in relation to their height. This means that, without restraint, walls are susceptible to buckling forces, a fact which must be taken into consideration when building or renovating. Support must be provided and this is achieved by securing floor diaphragms to external walls and strapping partition walls to perpendicular façade walls.

When such restraint is missing, inadequate or defective, walls can start to bow, bulge and/or lean. This telltale symptom of lacking lateral restraint should never be ignored and needs swift intervention to prevent the damage worsening and even becoming dangerous. It is most often older structures that display the common issue of bulging brickwork.

When the façade of a building has become disjointed from its main structure, the insertion of a series of load sharing structural restraint ties is the easiest and most effective way to remedy the situation. Installation is simple, each retrofit tie rod delivering the required reconnection and enhancing the resistance to buckling and thrusting forces to restore structural integrity.

As all structures are different, there are many types of lateral restraint system. When used for strengthening and reconnecting masonry wall junctions, we recommend our Extra-Long Structural Repair Ties, which allow you to quickly transfer lateral forces back to the buttressing walls. Made from marine-grade stainless steel, these crucial components are guaranteed to resist strongly against corrosion, meaning they will provide active, maintenance-free service for many years to come.

Our structural repair ties are sold in cost-effective and convenient packs of 10 ties. Check the product page for more information and to place your order.

Home and Dry: Tanking Membrane from Twistfix

All too soon, summer has given way to autumn and the rain has already made its unwelcome appearance! Heavy rainfall is often cited as a cause of basement leaks but the fact is that it usually just reveals an existing problem. Twistfix supply a wide range of professional basement tanking solutions, including cavity drain membranes.

Baseline Mesh Membrane Kit

All underground spaces must be properly protected against the ingress of moisture, which can cause all sorts of structural issues as well as posing a danger to health. When a basement is to be used as a working or living space, the need to protect the area from water is more important than ever.

Basement conversion is a popular method of increasing space. Other options, such as upgrading to a bigger property or extending into outdoor areas, can be costly and impractical; converting a basement is a simple and cost-effective alternative.

Cavity drain membrane is a necessary aspect of basement conversion. The system creates an air-gap between the wall/floor and the membrane itself, allowing water to pass behind it into a drainage channel and pump-housing sump. Water never comes into contact with the interior of the basement, ensuring the conversion is protected.

Installation is simple and involved fixing the membrane in place before overlaying it with battens or other framing system. Plasterboard can then be successfully applied to provide an area ready for finishing and decoration. Along with the membrane, Twistfix can supply all of the necessary ancillaries including waterproof plugs and plug seals, allowing for the most professional installation.

For a limited time, you can make big savings on one of our most popular basement tanking products: the Baseline Mesh Membrane Kit. Find out more details on the product page...

Condensation Confron­ta­tion: ThermalDry Paint

Damp can become an issue in all types of properties and for many different reasons. One of the most common causes is condensation and Twitsfix offer a range of solutions to the problem, including ThermalDry Anti-Condensation Coating.

ThermalDry Anti-Condensation Coating is a purpose-developed product which comprises a water-based acrylic emulsion paint. The formula incorporates myriad small glass beads, each of which is completely hollow; these beads allow the paint to act like a Thermos flask, using a reflective process to block thermal energy.

When thermal energy is reflected in this way, the masonry walls are protected from damp-causing condensation. Surfaces that are generally at a low temperature, such as walls, are more prone to condensation; ThermalDry fixes the issue by lowering the dew point by increasing this temperature.

Two coats of ThermalDry must be applied to create the most effective barrier. The first coat is applied in a horizontal fashion then, after up to four hours of drying time, the second coat is applied perpendicular to the first. Before applying the formula, it should be gently stirred by hand to disperse the glass beads evenly.

As well as protecting against condensation, ThermalDry also delivers an effective barrier against mould formation. It can be applied to internal or external walls, directly onto brick or concrete and over existing plaster and paint.

ThermalDry forms part of our portfolio of anti-condensation products. Find out more details on our website!

It's Woodworm Season Again! Solutions from Twistfix

The warm weather encourages us all to get outside but it is not only people who enjoy it: woodworm beetles are starting to emerge as well! Cases of woodworm are once again on the increase and professional builders should be ready to deal with upcoming contracts by stocking up on woodworm treatment from Twistfix.

Woodworm Treatment Kit

If you are a home or business owner, you can use our Find-A-Contractor service to make sure that your property is treated using Twistfix products. The term 'woodworm' covers a variety of wood-boring insects; the most widespread is the common furniture beetle. As well as furniture, these creepy-crawlies will also readily infest floorboard, rafters and skirting boards. Here's how to spot the issue:

  • Holes in timber.
    The larvae of wood-boring insects burrow deep into the timber, remaining there for many months. They survive by eating the timber as they burrow through it, before pupating and emerging as adult beetles during the warmer months. The beetle exits the timber to breed, leaving a small yet easily-visible hole.
  • Frass.
    This is the second sign to look for if you notice holes in timber. As a beetle eats its way out of the timber, it will bring with it a small amount of frass, a fine powder like sawdust. This can be found near to exit holes and is a telltale sign of an active infestation.
  • Damaged timber.
    The burrowing of larvae through timber weakens the material and can cause it to become brittle and flaky.
  • Beetles.
    Though occasionally spotted alive from May to October, it is just as common to find dead beetles in the area of infestation.

Twistfix supply a collection of woodworm treatment options. Each option is based on a micro-emulsion insecticide which comes in concentrated form. The product is registered for use by professional builders only and can only be supplied to addresses on the UK mainland. For the ultimate in cost-effec­tiveness, we recommend our comprehensive kit.

Be Kind to YOUR Brickwork this Summer!

The summer weather has got the whole of the UK in a good mood but spare a thought for your brickwork. Though it can't complain about the heat, it will nevertheless show its displeasure if not properly cared for!

Crack Injection Mortar 

Hot sunshine causes thermal expansion pressure to build up within the bricks, causing cracks to appear.  These fractures, if left untreated, will steadily deteriorate, possibly resulting in a loss of structural integrity and the ingress of moisture. Filling cracks in brickwork is vital task that reduces the risk of dampness and instability. The task is made easy with Crack Injection Mortar from Twistfix; each kit contains 250g of pre-coloured injection mortar and a syringe with extension tube. Check out our step-by-step guide below.

  1. Prepare the area by making sure that there is no dust, dirt or other debris in the cracks to be filled. The product works best when bricks are pre-wet but not soaked.
  2. Mix the specified ratio of water and powder together
  3. Fill the cracks using the product; this operation is facilitated with the supplied syringe and nozzle. 
  4. Once dry, the product leaves bricks ready to be sanded, shaped and modelled; this can be done up to 12 hours after application
  5. Clean tools and spillages using fresh water

Crack Injection Mortar is available from Twistfix in a range of different colours in order to match any style of brickwork. Only natural pigments are used and the product displays excellent adhesive charac­te­ristics.
