Tanking repair on basement wall subject to underground soil‼️

This is a tanking repair on a customer’s basement wall that had issues with penetrating damp from a tanking system that had deteriorated over time and eventually failed.

On inspection, we could evidently see an issue with the basement wall in particular lower down at the weakest point of the wall where the wall meets the floor and also in the centre/middle of the wall.

Repair:
- Contaminated plaster/render removed from floor to ceiling height✅
- Application of a Wall to floor fillet joint using a specialised tanking slurry to form a strong waterproofing barrier✅
- 2 coats of tanking slurry to physically block groundwater and salts from entering the internal space ✅

This repair is a type A waterproofing system that is highly effective for basement walls that are underground by completely changing how the wall/building handles water pressure.

Wall will be allowed to cure for at least 7-14 days before re boarding/plastering⏳

Improving your indoor air quality creating a healthier living environment‼️

This is an installation of a Positive Input Ventilation system (PIV Unit) to tackle condensation/mould growth.

Installation of a PIV Unit would introduce a better quality of air and in turn controlling condensation and preventing mould growth.

A PIV Unit draws fresh air from outside into the unit in the loft, where the air is filtered and supplied into the home through the ceiling diffuser. The unit pressurises the home, helping to dilute, displace and replace the moist, stale air with fresh, filtered air.

Before installation we ensure that the loft is suitably insulated and is well ventilated.

PIV Unit benefits:
- Help reduce humidity levels, controlling condensation and preventing mould growth
- Removes indoor and outdoor pollutants from the property and improving indoor air quality
- Low energy consumption
- Benefits asthma sufferers

Damp proofing repairs to old internal single-brick walls‼️

Our customer contacted us regarding ongoing salt contamination and decaying skirting boards along internal walls separating the living area and passage.

Following our inspection, we ruled out radiator pipe leaks and identified that the walls had been plastered directly over the original black mortar, leaving them vulnerable to damp and salt contamination.

Repair:
- Removal of contaminated plaster and mortar✅
- Installation of a Damp Proof Course (DPC)✅
- Application of a damp proofing membrane to create a physical barrier against moisture and salt contamination✅

Plastering or standard dot-and-dab dry lining techniques can be used just 24 hours after treatment⏳

A long term solution put in place to protect the internal walls from further rising damp and salt contamination issues✅

RISING DAMP REPAIR‼️

Our customer contacted us regarding damp issues affecting their passage party wall and small internal old porch wall. They were experiencing crumbling and flaking plaster to the lower sections of both walls and wanted a reliable, long-term solution.

During our inspection, we first ruled out any potential leaks from the radiator and associated pipework. Moisture readings were then taken, revealing elevated levels of moisture at the base of both the party wall and the internal porch wall.

The affected areas showed clear signs of deteriorating plaster and salt contamination, consistent with rising damp.

We also identified the original black mortar, suggesting the walls may not have a modern damp-proof course (DPC) in place and could still be reliant on the original construction methods.

Repair:
- Removed contaminated plaster and mortar✅
- Installed a new damp-proof course (DPC)✅
- Applied a damp proofing membrane to provide a barrier against residual moisture and salt contamination✅

Following completion of the damp proofing treatment, the walls can be replastered or finished using standard dot-and-dab dry-lining techniques after 24 hours.

Addressing the underlying cause of damp and treating salt-contaminated surfaces is essential to achieving a durable, long-lasting finish.

RISING DAMP REPAIR‼️

We were contacted by a customer to inspect one of their rental properties following reports of damp issues affecting several original ground floor walls.

Inspection:
On our inspection, we identified significant signs of hygroscopic salt contamination and moisture related deterioration. The plaster was crumbling in several areas throughout the ground floor living area, with elevated moisture readings detected along the lower sections of the affected walls.

Repair:
- Removal of contaminated plaster and render✅
- Installation of a damp proof course (DPC)✅
- Application of a damp proofing membrane to create a protective barrier against moisture and salt contamination✅

This remedial treatment is designed to help protect the walls against rising damp and salt contamination, providing a long-term approach to restoring and safeguarding the affected areas.

Following completion of the damp proofing treatment, the walls can be replastered or finished using standard dot and dab dry lining techniques after 24 hours.

This is the application of internal insulation without the need to hack off existing plaster‼️

This insulation is a specialist internal wall insulation system designed to help improve the thermal performance of external cold walls. It helps reduce heat loss, improve the internal surface temperature of walls and create a warmer, more comfortable living environment.

One of the main benefits of applying internal insulation is that it can help reduce cold spots and condensation associated with cold external walls, while also improving energy efficiency and potentially reducing heating costs. It provides an effective solution for upgrading existing walls with minimal disruption, helping to improve the comfort and overall efficiency of your home.

Walls can be plastered 24-48 hours after the application⏳

Damp Proofing Treatment for protection against penetrating and rising damp‼️

Our customer contacted us regarding damp issues affecting the lower section of the chimney breast, the rear external stone wall, and the upper section of the rear wall, which had experienced problems over the past few years.

Following our inspection, we identified a combination of penetrating damp and rising damp/hygroscopic salt. We first inspected the external areas of the property, including the guttering, downpipes and external render, and recommended that necessary remedial works to the help reduce the risk of further penetrating damp.

High moisture readings were also identified around the lower chimney breast and external wall, with evidence of salt contamination associated with rising damp. The property had previously had a damp proofing system installed many years ago, which had deteriorated over time and was no longer effective.

Repair:
- Contaminated plaster, render and mortar removed from floor to ceiling height ✅
- New DPC (Damp Proof Course) installed ✅
- Damp proofing membrane applied to provide a salt and moisture barrier ✅

This treatment is designed to help prevent moisture rising through the walls, reduce the effects of penetrating rainwater and protect internal decorative finishes from salt contamination associated with rising damp and the chimney breast.

The customer has also been advised to regularly maintain guttering and downpipes, ensuring they remain clear and free from damage to help prevent future water ingress.

Walls can be plastered or standard dry lining dot and dab techniques can be used 24 hours after the damp proofing treatment⏳
