The building had lots of leaks. The carpets/walls as well as the warehouse got inundated with water when there were heavy downpours of rain. The problem was that the down pipes and box gutters were rusting and corrosion had made holes through the guttering. The exterior cladding being a Besser block had become porous somewhat and the control joints seal had deteriorated to the point were water could pass through it.
We had to repair all the box gutters with sheet metal as well as lay a waterproof membrane down with UV qualities so that we could maximise the life of the gutters as the client did’t want to go to all that expense. The old control joints were cleaned out and Sika flex put in its place. The building was then water blasted cleaned of dirt/oil and painted. Unfortunately this is the only photo I have.
