Rising Damp usually occurs when unprotected porous materials (e.g. bricks and stone) come into contact with damp earth.
Damp often leads to timber decay, particularly in older properties with unprotected timbers.
Damage is caused to plaster and rendering as a result of hygroscopic salt contamination.
The moisture present often increases the conductivity of the walls, resulting in increased heat loss from the property.
The health of you and these around you can be put at risk due to the increase in fungal and mould growth spores. Damp can affect all unprotected walls, whether internal or external.
Methods of control vary because there are four main sources of dampness:
- Rising damp
- Penetrating damp
- The weather
- Dampness caused by plumbing
Our fully trained and experienced surveyors will correctly diagnose the nature of the problem and recommend the most effective damp proofing system for your particular problem and property. You will also have peace of mind and an insured long term guarantee for the work carried out.
Rising Damp is cured by:
Water based fluids are pressure injected into the walls to combat the damp. Pressure injection works best in a sound wall of fairly uniform porosity.
This grouting type of material is ideal for many applications, particularly where a good sized bed-joint is in evidence. The damp-proofing agent is carried into the porous mortar beds and rubble by the Rising Damp, where it crystallises to form an impermeable barrier to control subsequent water rise.
The cream is introduced into a series of holes drilled into the mortar course by the means of an application gun. Once the cream is installed, it cures to form a water repellent resin which prevents damp from rising up the wall.
In addition to injection damp proofing we can offer a range of membrane systems.
All forms of specialist re-plastering undertaken by our own in house trained plasterers.
Tanking provides a cementitious barrier to prevent water ingress below external ground levels.
Rentacure offers a water-repellent treatment for brick, concrete and stone walls. It is a deeply penetrating cream that is applied to the wall surface using a roller or brush. Once the treatment has been applied to the wall surface in a single coat, it will permeate deeply before curing to form a water-repellent barrier. The product is BBA approved 25 years. Typical applications for protecting against penetrating damp and rain penetration. Improves the thermal resistance of masonry by keeping it dry, improves the performance of cavity wall insulation by protecting it from moisture and improves flood resistance of masonry.
We offer a wide range of products to combat the effects of condensation including mould removal and prevention kits.
