Brickwork

Our approved methods of rehabilitation

• Rehabilitation of brickwork, replacements of the bricks, restoration of the joints
• Joining, anchoring and bracing as protection for cracks and safeguarding buildings of natural stones
• Void compaction to stabilise and strengthen brickwork
• Injection of cracks with filling material such as reaction resin, cement suspension, cement lime or other suitable filling material
• Elimination of humidity and salt damage
• Outside protection of walling in contact with soil, with bitumen thick layering, bitumen welded lanes, defensive top plaster or sealing sludge bound by cement.
• Cleaning of facades made of mineral construction materials
• Outer protection by gel film (film protection)
• Horizontal protection by mechanical processes and injection
• Façade insulation

Quality with a reinstatement design from WELS

1. Survey and documentation of damages
2. Testing at the surface
3. • Quantitative Assessment of harmful substances (Chlorides, Nitrates, Sulfates)
   • Assessment of moisture and hygroscopicity at drilled cores:
   • Assessment of the type of brick
   • Assessment of capillary water absorption
   • Assessment of sorption moisture
   • Assessment of pore volume
   • Testing of swellable clay and assessment of the hygric moisture expansion and shrinkage
   • Assessment of conservation by using standard preserving agents
   • Recommending a reinstatement concept of rehabilitation and conservation measures due to preservation orders.
