Wall ties

REMEDIAL WALL TIES INSTALLATION & REPLACEMENT

A Cavity Wall consists of two leaves of masonry connected together with Cavity Wall Ties.

Typically, Cavity Walls are constructed with an outer skin of brickwork, a 50mm wide cavity, and an inner skin of brickwork or blockwork, the average total thickness commonly being 250mm to 300mm.
The two skins are tied together with Cavity Wall Ties, usually 900mm apart horizontally and 450mm vertically. Extra ties are installed around window and door openings

WALL TIE SURVEY AND REPLACEMENT

If suitable/required, the exact position of the Wall Tie can be determined using a metal detector and then drilling a small hole using an endoscope to examine their condition. If ties are corroded or if there are insufficient ties, a suitable type of replacement wall tie must be installed. Corroded ties will need to be cut out of the outer skin to prevent further cracking, either by complete removal, bending back into the cavity or by isolation.

D.J.Mackay & Son carry out Cavity Wall Tie inspections and have a wide range of remedial strategies to choose from in the event that Wall Tie replacement is deemed to be required. Our remedial Wall tie Service usually carries a long term Guarantee from the company and may be subject to the issue of further insurance backed guarantees (Guarantee Insurance) if required.

Rendering

External rendering is the process of applying a smooth or textured external finish to outside walls. There are many different types of finishes that you can choose from and we are on hand to discuss which finish we think will best suit your property. The most common external finishes are as follows: Tyrolean: This form of render provides a protective and decorative layer as it is a coloured or white cement based mix. It can be applied by hand or most commonly by a power operated machine. It is popular because it gives a honeycomb textured finish and it can be repeatedly done until the preferred texture is achieved on the external wall. Pebble Dash: A popular choice whereby smooth or angular stones are thrown or “dashed” onto the topcoat of render whilst it is still wet, allowing the pebbles to stick. There are many different colour mixes to the stone and different colour dyes that you can add to the render to suit the stone, we can provide colour charts on request. It provides a weathering surface. Fine Down: Fine Down allows you to have a smooth finish and is used extensively on external walls. KW Plastering has worked extensively on all forms of external rendering, building up a large portfolio of work in the process. External walls are the first thing that people see when they arrive at your property so you want the job carried out by professionals
