Brickwork inc DPC’s and Cavity trays

 

 Northampton Builder Door Profile First the existing brickwork was cut out allow the new internal skin to join the existing internal brickwork, this maintains the cavity and stops the cavity being bridged which cause damp problems. Wall starters were then fixed to the existing brickwork. We prefer to use “Wall Starters” rather than physically teething into the brickwork because the brick size, the gauging on the existing brickwork is not consistent and if there is any settlement the toothed bricks are likely to break which would be a costly repair. Where as if settlement occurs  and wall starter are used there is no damage as the straight joint where the 2 walls meet should be filled with a flexible water proof sealant. Anyway………………..

The openings and bond were set out and profiles installed.

Northampton Builder Cavity TrayThe next job was install the damp proof course (DPC) and cavity tray. The damp  proof membrane (DPM) / Radon Barrier from the slab is brought through to the outer skin of brickwork, a block is then laid on the inside skin. Next a 450mm wide DPC is laid on the brickwork lapping up to the next block course creating a tray, another block is laid on the inside skin. Next a course of bricks is laid over the DPC and a weep outlet placed in a joint every 1.5m

Northampton builder  blockwork The brickwork then proceeded, building the outer skin 1st then “backing it up” with the blockwork installing  the cavity insulation as work progressed. The lintels were bedded on and another cavity tray install exactly the same as on the DPC. The wall plates  were bedded on the blockwork at the correct height and the brickwork to the gables continued  building in the 1st floor window profiles and install the lintels. The brickwork to the Gables could not to finished until the roof is cut, however the cavity closers were install the the openings, it is good practice to keep the brickwork, blockwork and cavity  dry.

Extension & Loft Conversion Foundations & Over site.

Northampton Extension Loft ConversionThis is a recently completed Home Extension and loft conversion. The Bungalow was extended 2.3m out the back, 3.3m to the side and a 1st floor constructed to create a loft conversion.

The 1st part to this project was the Groundwork, Foundation and Over site. The fence was taken and conservatory demolished. Next the Ground was reduced to approximately 450mm below finish floor level (FFL) to allow for hardcore, insulation, concrete and screed.

Brickwork Under ConstructionThen the building was set out with lines and profiles, Foundations were dug and inspected by building control before concrete was poured. Next the Drainage under the over site was installed leaving tails out of the building to connect on to at a later date.

The Brickwork was then Built up to Damp Proof Course (DPC) bridging over the drains with lintels. 150mm of hardcore was laid and compacted followed by 25mm soft sand blinding, then 1200 gauge Damp Proof Membrane laid bridging the cavity to create a radon barrier. 100mm of insulation was cut and installed before building control inspected the over site.Northampton Oversite Once the over site was inspected the floor slab was concreted which completed the 1st stage of this project the site strip, Foundations, Brickwork up to DPC and Over site.

Repairs to Impact Dammaged Property

Impact Damaged Building


This is one example of an impact damaged job completed recently. A car hit the building at about 70mph causing the brickwork to move across the DPC into a door opening about 600mm leaving the building structurally unsound, the works we completed follow.



Impact Damaged Building Propped Up
First of all the roof and the remaining brickwork in the gable had to be supported with acrows needles and strongboys to enable access to rebuild the the damaged brickwork.




Then the damaged brick and stonework was cleared setting aside any re-usable bradstone.
Before the brickwork commenced around 15 mortar samples were provided to the client and a brick match chosen.

Impacted Damaged Brickwork Repaired
The blockwork was built first to quickly secure the property and take some of the roof and gable load. We couldn't find a good "bradstone" match so used the amount salvaged stone to build a panel under the window and re-build the remainder in brickwork. The client was left with a very good match to the existing brick and stonework.
