Last year, SealteQ performed life-extending maintenance on the VvE building on William Boothlaan in Amstelveen. The life-extending work involved repairing concrete damage to roof edges, consoles, ceilings and edge thickenings, replacing the wear layers on the gallery floors, and removing asbestos-containing joints. This extensive project involved numerous repairs and maintenance tasks carried out by our specialists.
VvE building W. Boothlaan in Amstelveen repaired
Repairing concrete damage
The life-extending work on the VvE building 162-336 on William Boothlaan began with mapping all damage. The concrete roof edges, consoles, ceilings, and edge thickenings were thoroughly sounded and checked for loose sections. Subsequently, all identified loose concrete parts, concrete damage, and similar issues were removed by cutting and chiseling behind the reinforcement. After removing the loose concrete parts, the damaged areas were cleaned, made dust-free, and pre-moistened. The repair mortar was then applied, and the repairs were kept moist to prevent accelerated drying.
For some concrete damage, it was necessary to chisel out the damaged areas to at least 10mm behind the reinforcement steel. Subsequently, adhesion strength tests and inspections of the reinforcement steel were performed. The exposed reinforcement steel that had corroded was mechanically de-rusted and cleared of all loose rust. The damaged areas were then thoroughly cleaned, made dust-free, and generously moistened. Following this, the reinforcement steel was treated with a single-component corrosion-protective coating. Where necessary, auxiliary formwork was created, and the concrete damage was repaired using R3 repair mortar.
Life-extending Maintenance
In addition to repairing the concrete damage at the VvE building 162-336 on William Boothlaan, asbestos-containing sealant joints were removed and replaced with non-harmful sealant joints. The concrete components on the gallery side were recoated. Subsequently, the existing finish on the gallery floors was replaced with a waterproof polyurethane pour layer, a new drainage floor, and an impact and wear-resistant trowel floor finish. Scaffolding was used to access the areas requiring repair, coating, and gallery floor replacement. Thanks to SealteQ’s work, the building’s lifespan has been extended for several years. The repairs were carried out by SealteQ in accordance with the obtained
KOMO process certificate BRL 3201 and CUR recommendation 118.
