Common Repairs & Restoration Techniques
It is our objective here at Trillium Dell to perform the best repairs possible on your timber frame or log structure. Through years of practice, study, and refinement we have developed a multitude of repair methods for almost every situation in timber frame and log structures. Working with our engineering and design team we can develop the appropriate repair for situations that require structural analysis, and shop drawings. Our services range from simple single piece replacements or repair work to whole building repair, including dismantle and re-erection. Our crew of timber frame carpenters is one of the most qualified and experienced crews in the nation for heavy timber repair and restoration work.
Sill repairs and replacement is one of the most common projects we undertake for many types of structures. Settlers to the Midwest often did put adequate foundations under the buildings they built, subsequently many perfectly sound structures have rotted and compromised sill systems. We often lift the entire structure so that a new foundation and sill system can be installed, or replace portions of the damage sill by lifting sections of the building at a time. We also provide tuck pointing and masonry services to relay limestone and sandstone foundation walls as well as veneering original stone back on a poured concrete wall or block wall. Trillium Dell can provide a complete lifting and moving system using our state of the art Enerpac hydraulic jacking system to repair foundations and sill systems of buildings.
Tornadoes and straight line winds can rip the gable end off of a barn or the steeple from the church belltower. Trillium Dell is uniquely qualified to deal with any type of disaster restoration to your heavy timber structure. With in-house engineering, project management and design we offer full service restoration contracting to perform your repair. Many of the structures we have restored have been damaged by lightening, floods, high winds, and fire. Often these structures are assumed to be beyond repair. However with a combination of structural epoxy’s, mechanical fasteners/hardware, and our joinery techniques there is not a building we have ever been unable to restore or repair.
Structural epoxy’s are often used where we need to rebuild damaged or rotten pockets or places in the timber no larger than a softball in an average size timber. Often this is in a mortise or tenon location or post bottom, where bearing is critical. Non-structural epoxy’s are used in much larger sections of the frame, in most cases these epoxy’s are used when we need to rebuild an area to ensure a flat surface for siding or provide a better base for nailing. Concrete epoxy is used in almost all of our projects for fastening the frame to the new existing foundation. Our crew has the appropriate training for the proper use of thee epoxy’s, receiving periodic training from companies such as Hilti.
Wood to wood repair by in far revolves around the use of scarf joints, scarf joints are typically around 2’ long and are some form of a lap joint with pegs, and sometimes screws. Typically we utilize a stop played wedged scarf or a bladed and cogged scarf for our repairs. There are of course many variations of these joints and we use multiple adaptations in our repairs of buildings. It is important us that we retain as much of the original building fabric as possible when we repair a building.
