CASE STUDY 1
This unusual property is just outside Reading with a 300 yard river frontage running through the grounds. Built in the 1930s as a small weekend fishing cottage it was extended to its present size during the 1950s. Every so often the house becomes an island when the river overflows to approx 3 feet completely encircling the property.
 Hence the design of being build on a raised concrete platform enabling the water to run around and under the property.
Our client a  property developer that had used our company services before asked for a complete  survey on the best method to upgrade the exterior brick walls that was a mixture of different bricks, and very badly eroded pointing., 
As the property gets flooded on average every 18 months he also needed something to protect the RC Raft.

*    Cavity wall insulation installed

*    2 coat thermal rendering to all brickwork areas.

*    A primer base coat sprayed to all rendered areas

CONCRETE RAFT

there fuel bill was  to high.  Our survey revealed cavity wall tie failure on 1 wall, the sand faced fletton bricks had extensive frost damage on all elevations
( hundreds in fact ) , no cavity wall insulation, The wood shiplap on 3 elevations was rotten and was doing nothing to contain the heat in the property. Rafters
adjacent to the shiplap was also rotten and wood need attention. on all elevations the ground was bridging the DPC and would need to be reduced.

This house was originally 2   cottages in the 1800s converted into one large house around the 1950, and was a mixture of brick and
stone and blocks.

There was extensive cracks in many areas and some was serious in the fact that the brickwork had cracked through to the inside causing
considerable damp problems. Our client had recently purchased the property and had removed the climbing ivy that was covering most or the property. Although ivy looks very  nice on certain buildings it does cause a considerable amount of damage if left unchecked
