Solving damp problems
Whatever you might think, fortunately most damp problems ARE NOT caused by rising damp and DO NOT require expensive solutions.
To discover the cause of your damp problem ask for us a Damp Survey.
Possible causes of damp
- Broken or missing roof tiles and ridge tiles.
- Condition of chimneys and flashings
- Blocked guttering and downspouts.
- Leaking flat roofs
- Condition of brick work, stone, mortar
- Cracks in masonry
- External timbers, windows and doors
- Poor ventilation
- Air vents, position and condition
- Blocked drains
- Damp course missing or failed
Solving damp issues
- Identify the source of the water-moisture causing the damp.
- Eliminate the source. A damp course is added only if necessary.
- Ensure good ventilation.

Damp proof treatment we provide
For damp proof injections we use Ultracure, one of the leading products on the market for the control of rising damp.
The cream is applied into a series of holes drilled into the mortar course. From here the low molecular weight Silane effectively migrates into the masonry pores and fully passivates across the mortar joint as the cream reverts to a liquid phase. Upon curing a hydrophobic chemical damp proof barrier is formed in-situ. Curing of the DPC starts immediately with the final cure taking 2-6 weeks depending upon wall thickness.
Extensive field experience with this technology demonstrates that Ultracure will perform as well as any conventional liquid injection system against rising damp.
After treatment we replasterthe walls and if necessary we use a BBA Approved, fibre reinforced, lightweight, cementitious plaster.
Perlite lightweight aggregates replace a proportion of the sand to improve thermal resistance and reduce condensation. Special waterproofing additives, along with a porous structure effectively control dampness and salt migration whilst allowing the wall to dry out.
It is particularly useful where improved thermal performance is required, reducing the risk of condensation on external walls or in basements.
The mortar between bricks can come out over time and this puts a property at risk of water ingress.
If your house settles over time you might find one or more cracks running up your brickwork. Befoe we repoint the cracks we use a method called stiching where we insert a horizontal steel bar to hold the brickwork togther and distribute forces.
