Crack stitching repairs masonry cracks by inserting stainless steel helical bars into slots cut across the crack in the mortar joints. These bars are then bonded with grout or resin. This technique restores tensile strength, prevents further cracking, and stabilizes the wall discreetly.

Arch repairs fix damaged masonry arches, which support weight over openings or in bridges. Damage often stems from age, movement, or material decay. Repairs can involve rebuilding, but modern methods often use stainless steel helical bars bonded into the existing masonry. These bars strengthen the arch, redistribute loads, and prevent further issues like cracking or sagging, offering a durable and often discreet solution.

A structural waterproofing membrane prevents water from entering below-ground or earth-retaining structures like basements, even under hydrostatic pressure. These specialized membranes, made from materials such as bitumen or polymers, create a continuous barrier (Type A) or work within a cavity drain system (Type C) to keep the building dry and structurally sound.

Installation of steel beams involves precisely placing and securely fixing (bolting or welding) heavy steel members into a structure. This process, guided by structural engineers, uses cranes and other equipment to provide essential support for floors or to create open-plan areas, ensuring the building's stability and safety.

Building structural timber floors involves installing horizontal timber joists (solid or engineered) between supports, precisely sized for load. These are then covered with decking (plywood, OSB) to form the finished surface. Proper ventilation, damp-proofing, and insulation are essential for durability and comfort.

Building a timber roof involves constructing the timber framework (rafters, joists, purlins) that supports the roof covering. This can be done via traditional "cut roof" methods or by installing prefabricated "trussed rafters." Designs account for loads like snow and wind, ensuring stability and drainage, often with engineering guidance.
