Defeat Damp with our DIY DPC Kit

Right on cue after a sweltering heatwave, the heavens opened and now it seems to have been raining for days! If any of this excess water finds its way from the ground into the brick walls of YOUR property, then you're going to be looking at costly, time-consuming repairs that are certainly going to put a damper on the rest of your summer holiday. This means that it's the perfect time to install a damp proof course (DPC) and Twistfix are right here by your side with the perfect product to do it with.

That product is one of our continual bestselling items here at Twistfix, testament to its superior efficiency, simplicity of installation and consistently competitive Twistfix price. The DIY Damp Proofing Cream Kit contains everything needed to create a professional, lasting damp proof course to stop rising damp in walls.

The comprehensive kit centres on eight 380ml cartridges of professional DPC which in itself offers a reliable rising damp treatment for brick and masonry walls. Formulated using a process of emulsi­fica­tion and therefore without the need for added thickening agents, the DPC included in our kit is sufficient to create a new chemical damp proof course that will protect up to 30m of single leaf wall or 15m of cavity wall.

The DPC is injected into pre-drilled holes along the bed joint selected for the DPC, where it immediately begins to migrate deeply into the pores of damp masonry walls, stopping rising damp in its tracks. All that's left to do is make good with sand and cement, which you can get on with right away.

As well as the crucial damp proofing cream, the kit also contains two SDS carbide drill bits of appropriate size, an extension tube and a heavy-duty caulking gun so you can get to work as soon as you've unboxed. We've even thrown in a pair of protective gloves to make sure you work safely.

Lateral Restraint: The Solution to Bulging Walls

As a property ages, it becomes more and more susceptible to structural weaknesses. Lack of lateral restraint between floor beams and external masonry can lead to the visible symptom of bulging walls: as this bulging process happens gradually over an extended time period, it is often not noticed until the damage is severe

In new build structures, walls are secured to floors during the building process and internal partion brickwork is  connected to the external walls, preventing bulging. When it comes to retrofit applications for older buildings, the traditional remedy was to run a metal rod completely through the building, connecting to point-loaded iron pattresses on the outside: an impractical, unsightly and ineffective solution in restraining the wall as a whole.

Twistfix supply a wide range of load-sharing lateral restraint products which are much less invasive than the traditional solution. It is a simple task to determine the positions of joists, pipework and wiring inside a building affected by bulging, after which Twistfix Lateral Restraint Bars can be installed, tying bulging masonry back to the internal floor structure and thus helping to restore structural integrity.

The retrofit installation of lateral restraints is carried out from the outside of the affected property, ensuring that a minimum of disruption is experienced. After the tie-bars have been wound into the timbers, polyester or epoxy resin is used to firmly bond the bar to the masonry wall.  When completed, the entire process leaves almost no visible trace, delivering strength and security to the structure while maintaining its aesthetic.

Of course, tying walls to the timber diaphragm is only part of the solution; the additional insertion of bed-joint reinforcement to strengthen the facade and retrofit wall connectors to tie it back to partition walls all serve to secure the wall in place and to prevent further bulges and bowing.

The Twistfix Bulging Wall Restraint Kit contains everything required to achieve professional results and forms part of our lateral restraint family of products.

Protecting the Past: Restoration of Heritage Structure

Twistfix products are often used as part of remedial plans to renovate and restore listed buildings. One such building is Hall Place, a Grade II listed building located in Portsmouth.


Portsmouth, in Hampshire, along with other exposed areas on the south coast such as Dorset and West Sussex, was one of the first regions in which cavity wall structures became widely adopted. Hall Place, which was built in 1796, is the perfect example of an early cavity wall structure in the UK: when a system of repairs and cavity wall tie replacement was proposed for the structure, Twistfix was the first port of call for the contractors, 1st Master Wall Ties.

Hall Place is built using yellow buff bricks, a prestigious material, sourced from nearby in Dorset. Comprising a 9" structural inner wall and a 4.5" outer façade of Flemish bond brickwork known as 'snapped header', the front elevation of Hall Place features a solid parapet wall. Careful inspection showed that the outer leaf of the cavity wall was out of plumb and exhibited a series of undulations between levels; the soldier course lintels had also failed, leading to cracked brickwork above windows.

The leaves of the cavity wall were reconnected, and the soldier course lintels pinned, using Twistfix helical cavity wall ties. As it was essential to maintain the appearance of the façade, our self-tapping cavity wall tie replacements were used: these ties are installed into the smallest possible pilot holes (just 6mm in diameter) which are subsequently filled to make them practically invisible.

Above the window openings, helical bars were installed. This bed joint reinforcement formed a series of deep masonry beams, enabling all vertical loads to be properly distributed on either side of the brickwork, repairing the cracks and preventing any further movement.

Masonry Repair Solutions: The Brick Pin Fixing Kit

Cracks can occur in brick and stone structures for a number of reasons and repairing these cracks is crucial to avoid further damage. Twistfix offer a comprehensive suite of masonry crack repair solutions, many of which are supplied in kit form to ensure that all of the required components are immediately available at once. One of these is the bestselling Brick Pin Fixing Kit.

The brick pin fixing kit from Twistfix contains everything required to effect quick, accurate and long-lasting masonry stitching, repairing cracks at junctions in brick and stone structures. An ideal retrofit solution for the tying layers of variable quality masonry to perpendicular walls, the kit represents impressive cost-effec­tiveness when it comes to concealed masonry stitching.

The brick pin fixing kit contains:

  • 10 heavy-duty masonry stitching bars. Each bar is one metre in length, has a diameter of 8mm and is manufactured using high-quality stainless steel, noted for its remarkable resistance to corrosion
  • One 10kg tub of WHO 60, a specially-formulated masonry repair bonding grout
  • One mortar gun with masonry pinning nozzle set included
  • One mixer paddle

Firstly, pre-drilled pilot holes are made. The holes are filled with WHO-60 polymer modified masonry repair grout, into which the helical stitching bars are inserted, bonding the reinforcement securely to the masonry. The result is strengthened, stabilised areas of wall failure, where tensile forces are evenly redistributed along the length of the helical bars.

Brick Tinting: The Science of Colour

Completely transforming the look of a property is not as difficult and complex as it sounds; at least, not when you use brick staining dye from Twistfix. A comprehensive collection of brick staining formulas is available and here we present a quick guide on how to use them with the utmost effec­tiveness.

Brick Coloured Repair Mortar

Brick Stain Dye

Crack Injection Mortar

Brick staining dye allows you to quickly, easily and permanently change the colour of porous brickwork and is supplied ready-to-use. Within the formula are pigmented powders of superlative quality, dissolved completely in fixative fluid. Once applied, the dye is absorbed deeply into masonry pores, creating a strong integral bond that results in a natural, vapor-permeable finish.

Brick staining dye is a ready-to-use product that allows you to permanently change the colour of porous bricks. Formulated using high-quality pigmented powders, which have been dissolved in a fixative fluid, the dye is deeply absorbed into masonry pores. This creates an ultra-strong integral bond, resulting in a vapor-permeable, natural-looking finish.

Brick tints are a superb addition to our extensive range of colour-match brick repair mortars and crack-injection fillers.  The dyes are supplied in containers of 1L of formula, enough to dye around 20-25 square metres of masonry (dependent on required shade depth and masonry porosity). Throughout the staining process, the masonry texture is unaffected. A patch test is recommended before beginning, in order to ensure correct shade and coverage.

Though supplied ready-to-use, brick tint formulas may be diluted (to a maximum 2 parts water to 1 part formula) in order to achieve a lighter shade. The dye is simply applied with a brush directly to the face of each brick and left to dry, after which further coats can be added to deepen the shade.

There are several shades available, along with a brick staining soot wash and a limestone tinting dye. For further information on these products, check the website or get in touch with our team.

For a complete solution, we recommend Twistfix Mould Remover Kit. This professional kit includes everything necessary to achieve lasting results, eradicating toxic mould and preventing it from recurring in the future.  The cost-effective kit contains:

  • 1 x 1,000ml Mould Remover Biocide Spray. The product is supplied in a ready-to-use spray bottle containing sufficient formula to treat ten square metres of wall surface
  • 2 x 100ml Fungicidal Additive. After treatment, mix 100ml of fungicidal additive with 5L of emulsion paint/10L of solvent or gloss paint and apply to the treated wall to prevent regrowth of mould
  • Gloves, Goggles and Sponge. These accessories will ensure you can work safely and efficiently.

Both Twistfix Mould Remover and Fungicidal Additive are available separately from the 'Mould Remover Products' section of our website, where you will also find information on our unique ThermalDry Anti-Condensation Coating. Don't let mould damage YOUR property: take action today!
