New warehouse floor installation at Great Yarmouth
Industrial Flooring Great Yarmouth
The warehouse floor was in a poor condition and required refurbishment to allow its continued use as a liquid chemical store.
Prior to our arrival on site the worst areas in the floor has been repaired by breaking out and reinstating using reinforced concrete. Unfortunately when this was installed it had been over watered which resulted in an excessive layer of laitance and a weaker slab.
As with all industrial flooring correct preparation to ensure excellent adhesion of the new resin floor was essential. We prepared the slab using a single head three phase grinder which removed the laitance from the new concrete but also served to reduce the heavy profiling on the old part of the slab.
Forming a liquid damp proof membrane
To help strengthen the weaker concrete Remmers Epoxy MT100 was applied thinned 10% to aid penetration into the concrete matrix. This was followed by the application of two further coats of Remmers Epoxy MT100 to form a liquid damp proof membrane. This was necessary due to the building having been constructed on an existing yard slab, something that is surprisingly common in industrial flooring. As a result it was unlikely that a DPM would be present, meaning that if one were not installed it could lead to osmotic blistering.
In the most profiled areas a scratch coat of Remmers Epoxy MT100 was applied to fill the profile of the floor.
Following priming minor defects in the floor were filled using a twin component filler and a bead of polyurethane sealant installed around the perimeter to isolate this potential point of movement.
Remmbers Epoxy WHG
Due to the use of the warehouse as a chemical store a chemical resistant industrial flooring solution was required. For this reason we specified Remmers Epoxy WHG as the most suitable form of resin flooring. The additional benefit of this material is that as well as being highly chemical resistant it can crack bridge, making it particularly suitable for old industrial floors such as here.
To provide the level of slip resistance required a 0.3mm – 0.6mm quartz aggregate was included in the first coat of Remmers Epoxy WHG, giving a uniform slip resistant finish.
Finally the expansion joints where reflected using a vacuum controlled floor saw and sealed using a polyurethane jointing compound.
