DAMP REPAIR SERVICES

Our expert damp remediation services include:

Repairing various types of damp (whether caused by rising damp, penetrating damp, plumbing leaks, roof/window/door leaks or flooding)
Damp proofing tanking systems, i.e. tanking of sub-terrainial structures like basements
Repair and installation of agricultural drainage systems around structures and by retaining walls
Remediating leaking concrete structures (concrete rooftops or floors, balconies & patios)
Please Note: we DON'T do "pap-en-lap" roof leaks, we do expert damp proofing!

The works process varies by damp challenge. E.g. for internal walls, the process is:

Expose brickwork
Prep work area
Injection treatment
Latex cementitious slurry after injection
New scratch plaster & prep for painting

TANKING SYSTEMS

Penetrating damp usually occurs where external ground levels are higher than the internal floor levels. Dampness within the soil bears against these walls and penetrates through them. Penetrating damp also occurs in floor slabs where there is a high water table and a compromised damp proofing membrane (DPC). This is particularly prevalent in basements, cellars and near structural retaining walls and requires a "tanking damp proofing system" of treatment to prevent further moisture ingress.

CONCRETE STRUCTURAL REPAIRS

Apart from damp proofing the areas damages by leaking concrete roofs, decks, patios or balconies, structural repairs may also be required when waterproofing concrete slabs. We have experience in:

Reinforcing slab stitching
Concrete column repairs
Beam spalling repairs

AGRICULTURAL DRAINAGE SYSTEMS

These systems are used both on agricultural land and around structures to remove excess water and maintain structural integrity. These systems can be surface or subsurface, and they play a crucial role in preventing waterlogging, salinity, soil erosion & hydrostatic pressure. They typically involve subsurface drainage (perforated pipes or gravel-filled trenches) to remove water away from structures to prevent issues like foundation cracking, water damage, and soil instability.

DAMP PROOFING PROCESS & SYSTEMS

Our general damp proofing procedure:

A professional, thorough on-site damp assessment
Detailed report issued, with findings, recommendations & a quotation if applicable
On signed acceptance of quote, the works is scheduled
Deposit invoice is issued a few days prior to commencement of works
Client provides electricity, water supply and toilet facilities for our team's use
Client removes all personal belongings and furnishings from the area/s to be treated
Team arrives per scheduled date and time to commence works
Area to be treated is prepared, e.g. we erect boards / plastic to seal off the area to prevent as much disturbance to other areas as possible
The area/s to be treated is cleared and stripped to expose damp to be treated
Treatment is applied as per the assessment/quotation specifications
Area is tidied up as best as possible; treatment is left to dry out for predetermined time
Progress invoice is issued for completion of "wet works"
Once dry, the team returns to skim and paint the treated areas (if applicable)
Final invoice is issued for completion of works

We make use of various appropriate damp proofing systems, including:

Heat/fusion application of torch-on membrane
Polyurethane systems
Cementitious damp proofing systems

Please keep in mind that we've refined this process over decades, since we stand by the quality of our work and guarantee it.
