This case study focuses on the repairs to the log cabin suffering from water ingress as a result of wet rot, open joints, and fissures in the timber. The Owner uses RSA, Borotreat and Timber inserts to effect essential repairs. 

Chigwell School in Essex is a Grade 1 listed building dating back to 1816. A leaking roof has led to long term decay to main structural elements of the roof structure. Using TG6 as a bearing surface it was possible to repair in situ the roof structure with minimal disturbance. 

The Ballycopeland Windmill in Millisle, Co. Down is prime example of low disturbance methods reducing the cost and time associated with making an essential repair. The main beam on the fan table supporting the rear fan had decayed and needed to be replaced. This case study outlines the repairs using TG6, Rotafix Structural Adhesive, Bonded in Rods and Timber Resin Splice.

The Coronarium Bridge in the basin of St Katharine’s is a cantilevered rising public footbridge with each side consisting of two arms and a counter-weighted section supported by a pivot on top of the portal beam.  Over the years the bridge has been subjected to the general usage, weather as well as the occasional knock from an errant boat that has resulted in a number of structural issues that have led to decay and failure. This case study outlines the repairs using TG6, Rotafix Structural Adhesive, Bonded in Rods and Timber Coatings.

Chetham’s Library, which was founded in 1653, is the oldest surviving public library in Britain. The building that houses Chetham’s is even older it was built in 1421. The beautiful old sandstone buildings house a magnificent Library with rooms lined with ornate oak paneling to the walls and ceilings. Previous attempts to strengthen the roof have failed. This case looks at the sympathetic strength upgrading using TG6 and carbon fibre plates.

The Sacra Infermeria in Valletta, is a 15th century building used as a Hospital and now an exhibition centre. The soffits, corbels and wooden roof needed structural repairs. This case study shows the stage by stage works completed

Kiddington Hall is a Grade II listed property. Low disturbance methods were used to re-establish the integrity of the floor joists with minimal impact to the decorative ceilings below using Rotafix TG6 Structural Grout.

The Malaysian Timber Industry Board’s (MTIB) iconic Timber Building in Tebrau, Johor Bahru, showcases Glulam’s almost unlimited design flexibility and structural strength

This case study will focus on the floor joists that had been ravaged by wet rot as a result of moisture from the walls being in contact with the end grain of the timber over a protracted period.

Reconnecting the floor/ceiling joists between the ground and first floors using timber resin splice method using carbon fibre plate and Rotafix Structural Adhesive.

The roof trusses of Clyne Castle were subject to prolonged water damage as a result of leaking guttering. This case study shows how new rafter feet were connected to the existing timbers.

The Tourand Creek Bridge south of Winnipeg on Highway 59 was selected as the first of its kind to undergo an innovative strengthening technique developed in conjunction with ISIS Research Canada. Upon completion, this 39-year-old structure was at least 30 percent stronger.

The timber in the lock gates from Newport Docks has suffered from erosion and their attachment to the mechanical fixings has been compromised.

Timber slip and fissure injection method being used to repair splits and shakes in oak beams.

 

Water ingress via the studs has decayed the hardwood timber beam and general wear and tear caused the lower edge of the beam to decay. Splicing in new timber with Rotafix RSA gives a reassuring repair.

 Water ingress into the end grain of a Glulam beam results in wet rot. Here is a step by step guide to casting a new beam end in Rotafix TG6 Timber grout.

The repair was carried out in two phases to reduce the temporary works. Shear connectors were fitted into slots in the side of the beam. Rotafix TG6 Timber Grout was poured via a hopper system into the steel shoe, this system will ensure that any water that enters the shoe in the future will not affect the timber beam.

Since installation the totem pole had suffered from a lack of maintenance to the original paint. In addition, the foot of the pole had been placed in what turned out to be a totally water saturated concrete shoe support which caused extensive rot to the buried foot of the totem pole.
