Floodwater damage to buildings | Checklist
Checklist An overview Flooding can cause significant damage to buildings and interior furnishings. In addition to the water damage to the basement walls, the contamination from leaked heating oil on the walls and floor substrates presents another challenge. To give you an overview of the first steps for the refurbishment of the affected parts of the building, our checklist for flood damage and oil contamination provides initial information for the upcoming renovation measures on wall and floor substrates.
2
1 Documenting floodwater damage • Make a detailed record of all affected areas, including damaged objects, parts of the building and outdoor facilities (type of damage, extent, description, etc.) and document with photographs. • Mark the highest water level reached on the walls and interior furnishings.
2 Determine structural integrity • Special caution with wooden-framed houses: Be sure to contact the manufacturer or a qualified expert, as plasterboard or wood fibreboard is sometimes used to stabilise the walls.
3 Pumping water away • As soon as the water level drops, the water in the building should be pumped out gradually and slowly. Pumping out too quickly can cause damage to the foundation and walls of the building. • If there are large quantities of water involved or if you are unsure, consult a specialist.
4 Rapidly removing mud • Dried mud is hard and can only be removed with great effort. It often causes damage to floors and walls. • The mud keeps the building structure damp. This can lead to mould growth and other moisture-related damage.
5 Remove wet objects such as wallpaper, floor coverings, etc. • By removing it quickly, the substrate can dry and the formation of mould and further damage can be avoided.
6 Checking the wall surfaces in direct contact with the ground / basement walls • After exposing the masonry work, the condition of the existing external waterproofing must be assessed. Cracks, voids and other damage are identified. • Check for damage to house entries and house connections.
7 Additional measures in case of heating oil contamination in the building •W ith the help of the fire department, the oil leak can be contained and disposed of properly. • If only a small amount of oil has leaked, the water level in the building should not be lowered completely. This prevents the oil from penetrating the entire building structure with the water. Remove the oil from the surface. • R emove the contaminated plaster/screed at least 80 cm beyond the contaminated area. •C lean the wall and floor substrates with a surfactant-containing cleaning agent ASO-R008. Deep oil ingress in the building structure: • Option 1: The affected area of the wall or floor must be removed and disposed of. • Option 2: The oil ingress is sealed in. For this purpose, we recommend our special epoxy resin ASODUR-SG3-thix.

Floodwater damage to buildings | Restoration plaster system
Restoration plaster system For masonry work damaged by damp and salt without additional waterproofing measures
THERMOPAL-ULTRA-white
ESCO-FLUAT
THERMOPAL-SP
AQUAFIN-i380
1. Substrate preparation 1 Remove the plaster from a minimum of 80 cm beyond the damaged area. 2 Chase out crumbly and salt loaded joints to a depth of at least 20 mm. 3 Use ESCO-FLUAT to convert highly soluble sulphate and chloride salts to poorly soluble salts. 4 Fill joints and voids with THERMOPAL-GP11 2. Horizontal barrier 1 Use AQUAFIN-i380 or AQUAFIN-F to create a subsequent horizontal barrier 2 Use ASOCRET-M30 to reseal the drilled holes 3. Restoration plaster system 1 For improved adhesion, apply the THERMOPAL-SP splatterdash coat as a semi-covering to the load-bearing substrate. 2 If required (e.g. high salt loading and large surface irregularities), apply the THERMOPAL-GP11 base plaster as an intermediate layer. Roughen up the surface horizontally for the subsequent coat of restoration plaster 3 Use the THERMOPAL-ULTRA-white restoration plaster to plaster the wall surfaces. 4 THERMOPAL-FS33 can be applied as a finish if fine plaster is required.

Floodwater damage to buildings | Cementitious waterproofing
Cementitious waterproofing With AQUAFIN-RB400 Cementitious waterproofing products such as AQUAFINRB400 are characterised by their versatility. The reactive drying is a major advantage in practice. This means, no matter whether it is raining, hot or cold, AQUAFIN-RB400 dries almost climate-
independently. And it does so particularly rapidly. The material can be reworked after just three hours and enables rapid construction progress that would be unthinkable when using bituminous waterproofing.
