Chemical Damp Proof Course

Water Based Silicone Injection DPC

A chemical damp proof course injected into the wall is a good way of preventing rising damp. The existing wall plaster will need to be removed. YourLondonBuilders.co.ukuse the Dryzone/Drytech chemical damp proofing system.

A series of 12mm diameter holes are drilled to the correct depth into the mortar joints at predetermined horizontal centres. A water based silicone cream is then injected into the holes.

YourLondonBuilders.co.uk then uses specialist plaster to seal the wall and prevent the appearance of hygroscopic mineral salt deposits. The specialist plaster also gives a vapour-permeable finish to enable the drying out of the residual moisture within the wall.

Sump Pumps

Basement Waterproofing Sump Pumps

YourLondonBuilders.co.uk have the expertise to install sump pumps combined with damp proof membranes which pump any collected water to an external drain.

This system is recommended for water proofing basements and cellars, as well as properties that are at risk from flooding.

We install a P20 Tanking System which works by directing any water in the cellar walls,down the outside of the membrane and channeling it into a sump and pump system in the floor.

The water is then pumped into the external mains once it reaches a preset level.

Ventilation is essential when designing water proofing solutions for basements. Good ventilation will prevent condensation and black mould growth. YourLondonBuilders.co.uk will advise you on the best options available

Cementitious Tanking

Cementitious Tanking for Damp Proofing

Our damp proofing specialists remove any existing cement render or plaster and then apply with three layers of cementitious coats to the walls. This seals the moisture within the wall and prevents any dampness from coming through. The walls can then be re plastered and decorative finishes can be applied.

YourLondonBuilders.co.uk most commonly uses this technique to control dampness coming through earth retained walls.

If the source of dampness is caused by a building defect YourLondonBuilders.co.uk will advise you on the best way to correct the fault.

A common cause of lateral penetrating damp is brick flower beds, rockeries and raised driveways which which are built above the level of the DPC in the existing property wall. Dampness will then spread horizontally to the internal walls of the building.

Other common causes of penetrating damp is badly deteriorated pointing and damaged external cement render coatings - all easily rectified.

Rising Damp

Rising Damp Treatment

YourLondonBuilders.co.uk has the expertise to diagnose rising damp, to identify what is causing it and subsequently correcting the problem.

Rising Damp can produce the following symptoms

  • Wallpaper Blistering or Peeling
  • Black Mould on Walls
  • Paint Peeling and Blistering
  • Tide Marks on Wall
  • Dark Staining on Walls
  • Damp and falling Plaster
  • Fungal Decay in Skirting Boards
  • Damp Patches on the Walls

YourLondonBuilders.co.uk will trace the source of the dampness - this may be due to faulty plumbing, broken drain pipes, poor ventilation and blocked or poor drainage.

If required a new Damp Proof Course will be inserted into the affected area.

Condensation

Eliminating Condensation

Condensation can be a major problem in some properties causing black and green mould to spread over walls, ceilings, furnishings and clothes causing significant health and breathing problems.

Invariably the main cause of condensation problems is poor ventilation. Property needs to breathe. Double glazing, sealed fire places, and modern flooring and poor insulation can all exacerbate the problem.

YourLondonBuilders.co.uk provide solutions to condensation build up using a variety of condensation control systems.

These range from simple air extraction units incorporating heat recovery systems to prevent drops in room temperature, to positive pressure ventilation systems which draws in fresh filtered air from outside and creates a positive pressure to circulate it gently around the property and displace stale contaminated air.
