Helitec Structural Services were invited to undertake strata building repairs on a block of 6 x 2 bedroom units in Coogee.
The building previously had works to restore some windows and facade on the northern and western elevations. However, the roofs, sunrooms, internal and external wall cracking the buildings waterproofing, soffits and painting were all in need of attention.
Helitec employed several disciplines for the completion of this strata building repairs project. Some areas included Brickwork; Carpentry; Coke Breeze Lintels, Concrete Repairs; Crack Stitching Repairs; Floor Topping; Guttering; Painting; Rendering; ResiTies; Roofing; Sill & Flashings; Roof Tension Ties replacement; Windows replacement.
Helitec completed carpentry works to Install 18 new windows, 6 of them were new Bay Windows. Repairs were carried out on other throughout the building windows.
The bay windows required extensive repairs to the framing as there was a lot of wood rot and mis-alignment. A fire rated sheeting to achieve 60 minute resistance to insipid spread of flame when ruling the window framing.
ROOFING, WATERPROOFING & GUTTERING
Helitec undertook roof repairs by replacing some valleys as they were showing signs of corrosion. Several gutters were replaced with a custom profile to match the existing gutters. The bitumen coatings on the roofs above the sunrooms were stripped and replaced with a torch-on bituminous membrane system. Th sunroom roofs were then painted white. All window frame openings were sealed to ensure a durable fixing of the new windows.
REPLACING COKE BREEZE’s & LINTELS
The fireproofing of the building was enhanced by fitting Coke Breeze infills above the new bay windows where they were cracked and spalling. This ensured each floor was protected from fire in adjacent floors. Where necessary corroded lintels above window openings were replace with Stainless Steel bars. Failing inner skin brickwork concrete lintels where replaced.
Several areas around the units were suffering from concrete spalling and reinforcement corrosion. Helitec removed concrete around any steel reinforcement that was visible. Any corrosion was removed and the reinforcement bars were treated with a anti-corrosion bonding agent. Repaired areas were strengthened using the Helifix® Stainless Steel Resitie Systems
