Remedial Cavity Wall Ties

Killan Structural Ltd have been involved with all aspects of wall tie survey and installation ever since the company’s formation in the early 1980’s.

‍We have gained experience fixing ties of all types, into every type of wall construction and are confident in our ability to provide the best solution to any given problem.
‍
‍Installing replacement wall ties in a uniform cavity wall is a relatively simple procedure and yet complications can easily arise through variations in cavity width, type and quality of the host materials etc. Every job becomes unique and our teams are equipped to deal with developments on-site.

Cavity Wall Tie Solutions

Survey

Typical Procedure:

The first stage of any job is a survey to establish the method of wall construction, the type, quantity and condition of any existing ties and any problems which may already have occurred.

Locate the ties using a metal detector and note their pattern and density
Drill inspection holes
View a sample of ties in the cavity using a high intensity borescope
Where necessary sample ties can be removed for further analysis

Action

If the ties are found to be corroded then we recommend a complete replacement using an appropriate tie of the correct length.

If the existing ties are a thick metal type which can cause problems with cracking the joints then these should be removed or structurally isolated.

If everything is OK then we will not recommend unnecessary work!

The guidelines for remedial ties are contained in BRE Digests 401 & 329. BSI DD140 Part 2

Any work which we do undertake is guaranteed for both materials and workmanship and can be insurance backed through the Wall Tie Installers Federation.

Wall Stabilisation & Lateral Restraint

Strapping external walls to floor, ceiling & roof construction, internal cross walls, party walls etc.

This is a major element of the work that we undertake and has been used to effectively stabilise walls in many different types of property.

Our knowledge and experience of several solutions means that walls which may once have been rebuilt can be restrained at a fraction of the cost, with minimal disturbance and without the need for unsightly external plates.

Our own design Structies for fixing to floor or ceiling joists or cross walls
Drillties to connect external walls to floor joists & installed from outside the property.
Resin bonded fixings into internal cross walls installed from outside the property
Front to rear tie bars hidden within the floor void and resin bonded into external walls
Crack stitch repairs to fractures in masonry. Often used in conjunction with reinforcement mesh when plastered or rendered
Stainless steel resin bonded pins to tie in stone jambs, door and window heads etc.
Bespoke engineered solutions that can be designed in conjunction with consulting structural engineers and manufactured in partnership with a trusted team of local fabricators

Crack Stitching & Masonry Beaming

We have extensive experience in the installation of masonry bed joint reinforcement. Stainless steel bars are grouted into mortar joints for a range of applications.

Crack stitching
Lintel reinforcement to stabilise brickwork above failed or omitted lintels
Masonry Beams and introduction of longer spans of reinforcement to assist lateral restraint. For instance to span across the stairwell on a gable wall between points of lateral restraint

Structie System

We have developed our own range of Structies for use in wall stabilisation schemes. Several standard sizes of Structie are available and others can be made to order to suit each job. They may be used to stabilise brickwork, blockwork or stone walls of solid or cavity construction.

The unique benefit of Structies is that they provide a solid fixing to both leaves of the external masonry.

Installation causes minimal disturbance and floorboards are lifted only where necessary. Where Structies run over joists, the joists are notched to accommodate the strap and allow refixing of floorboards.
