Summary: How to tie a new wall to an existing brick or block wall.

Tying to existing brickwork and blockwork when building an extension for example is a common problem our users come up against. Traditionally this job used to be done by a method called toothing out.
This means that the brickwork, or blockwork, is cut back to leave a tooth like shape, into which the new bricks or blocks were laid. This kept the integrity of the wall and also the strength, as the wall remained "in bond".

Its now possible to use a wall tie method which is so simple it takes all of the hard work out of bonding to old or existing work. The wall tie pack is simply bolted to the existing wall and wall ties are slotted into the rack every time it is required to tie into the new wall. The bond is as strong as the old toothing out method and it knocks days of the construction time. The wall tie method can be bought by clicking into the tool section below.
Before adding a new wall to an old one you must check with your building inspector to see if a vertical damp proof course is required between walls, and whether or not any existing cavity in the walls of the existing construction, needs to be continued into the new construction. Building regulations must be upheld at all times for your own, as well as any future owners, safety.
