Basement Waterproofing
A cavity drain membrane system can be applied in basements and cellars to improve functionality.
The cavity drain membrane system is a special high-performance polyethylene membrane which is extruded into a series of studs. These studs create an air gap behind the waterproof membrane. A welded mesh on the front of the membrane improves the bonding efficiency of the plasters and renders for dry and durable finishes.
The cavity drain membrane is watertight; resistant to high and low temperature extremes; chemically resistant to acids, alkalis, oil and solvents; and is approved for use in drinking water applications.
The membrane stud design provides a continuous air gap which isolates the damp wall from the new plaster and decorative finishes. It also improves ventilation of the wall, allowing for permanent dampness control.
Unlike traditional tanking systems which hold the water back, cavity drain membranes allow water to penetrate the structure but control it in the air gap before rerouting it to an appropriate drainage point.
If some cases, the membrane directs water flow into hidden drainage channels via a sump and pump system.
In properties at risk of flooding, a submerged sump and pump can be installed below the floor level. This will collect water penetrating through the walls/floor and pump it outside to an external drain.
Our works will provide a dry internal floor and wall surface, making the cellar or basement rooms of your property habitable.
Condensation and Mould Prevention
Condensation dampness is a condition that affects many homes and has probably become the major cause of ‘environmental’ dampness within a property. Condensation is particularly common in homes which are poorly heated and poorly insulated and usually gets worse in the colder winter months i.e. ‘the condensation season’.
There are different types of units that Maljon offer, but the main two we offer are the Nuaire Dri-Eco-Heat-HCS Positive Input Ventilation Unit and the Nuaire Flatmaster 2000.
The Dri-Eco-Heat-HCS and Flatmaster 2000 both offer a ventilation solution for the whole property, using the tried and tested Positive Input Ventilation (PIV) principle, where fresh, filtered air is introduced into the home at a continuous rate, encouraging movement of air from inside to outside.
Thermal Boarding
Thermal board can be applied to the walls to provide insulation and a warmer wall surface. This insulation conducts heat slowly, but it also prevents problems resulting from condensation.
Thermal insulation boards are available in various sizes and can be cut to fit a certain space. They are laid, glued, or fixed into position with the necessary fixings. Insulation boards are often made using rigid insulating foam with a thin sheet of reflecting foil fixed to one or both sides.

Damp Proofing
Rising damp refers to water travelling through porous building materials that are in contact with the ground. This causes the wall to draw water from the ground, which in turn evaporates into the atmosphere. This pattern continues, until the water reaches a height where it can no longer evaporate, meaning dampness will occur and remain in the wall.
Installing a Damp Proof Course
-
Holes are drilled in the mortar of the bricks at a specified height
-
Damp proofing material is then injected into the holes
A water-based silicone injection is considered the most effective damp proof course at preventing the rise of moisture through walls.
Re-plastering is often required after the insertion of a damp-proof course. New wall plaster will then prevent the migration of damp and salts from the wall to the internal wall decoration.
ISO-Therm Membrane
ISO-THERM is vapour permeable, but waterproof, thereby resisting any lateral damp transference, and stopping the subsequent natural surface nitrates and chlorides forming as an efflorescent salt. Because of its high thermal benefit, and the withholding of any natural damp transference, it is highly resistant to any formation of surface mould.
It is fixed in place with a unique ISO-THERM adhesive, normally trowelled onto the wall to a thickness of approximately 5mm, and with the ISO-THERM affixed and rolled into the adhesive, the overall finished depth after a direct plaster skim coat is around 10mm.
Timber Preservation
The most common species of woodboring insect in the UK is the Common Furniture Beetle. This species can be identified by the small, round holes they leave on the timber’s surface. In most cases, the fix is simple. Any structurally-weakened timber must be replaced with pre-treated timber. All affected surfaces should then be sprayed with a woodworm insecticide.
Other woodboring insects common to the UK include the Death Watch Beetle, House Longhorn Beetle, and the Powderpost Beetle. Whilst the Powderpost beetle can be treated in much the same way as the Common Furniture Beetle, House Longhorn and Death Watch Beetle infestations require a bit more.
Insured-Backed Guarantees
We offer a 10-year guarantee for our timber treatments*, chemical damp proof course injection** and our membrane systems.
In addition to our guarantees, we offer a 10-year insured backed guarantee with Accelerant Insurance UK Limited. This is a one-off fee in the unlikely event we go out of business and you need to make a claim against the work that we have carried out.
Once you have paid for your works in full, we will issue you the guarantee for your property. This guarantee is transferrable to the next owners of the property free of charge, however, if you would like the guarantee to be issued to a specific company or persons, we can reassign this with a fee of £35.00+VAT.
*We do not guarantee against Death Watch Beetle due to the Death Watch Beetle larva lives in the timber for a considerable amount of time, i.e. up to 8 years, the larva being deep-seated, infestations within the timber can continue for this period after surface treatment only has been carried out, thus causing extensive damage. In the unlikely case that the Timber Treatments cannot be guaranteed, this will be explained in writing in your report.
**In the unlikely case that the Damp Proof Course cannot be guaranteed, this will be explained in writing in your report.
