External Wall Seepage Repair
High-rise buildings, which are abundant in Singapore face an increased likelihood of external wall seepage when rainfall is coupled with high wind speeds at higher altitudes. We specialise in various methods to rectify external wall seepages.
Methods & Techniques
Sealant Work (Glazing)
Structural Silicone Glazing (SSG) is a cutting-edge technique that employs silicone sealants to directly bond various materials, such as glass, ceramic, metal, and other composite panels, to support frames. This is accomplished using peripheral adhesive joints. Beyond its role as an adhesive, the SSG also acts as a formidable weather barrier. It meticulously ensures that water doesn't permeate through the panels, safeguarding the structure's integrity.
In building maintenance and aesthetics, sealants are often the unsung heroes. They are chiefly used for sealing the gaps between cladding and window panels. Given the array of materials and architectural designs, many waterproof sealants and silicone solutions are available in the market. Depending on the specifics of the project, different application methods are employed.
The ultimate aim remains consistent – providing an economical solution without compromising aesthetics or durability. When applied correctly, these sealants offer a long-lasting, watertight seal, ensuring the longevity and beauty of the structure.
Sealant Work (Cladding)
In Singapore, where the weather conditions can be particularly demanding, external wall cladding is the building's shield. It offers protection against adverse climatic elements and plays a pivotal role in noise attenuation, acting as an effective barrier against urban noise pollution. Integral to the efficacy of these claddings is the use of high-calibre sealants, such as structural silicone, which are meticulously applied to bridge the gaps between cladding panels.
However, challenges do arise. Issues with failed joint sealants at critical junctures like leaky windows, building cladding, and flashings can be exasperating, often leading to significant weatherproofing setbacks. Yet, with the right application technique and quality of sealants, these problems can be effectively circumvented. When applied diligently, these sealants fortify the building against external factors and ensure its aesthetic appeal and longevity.
Waterproofing is paramount, especially in regions like Singapore, where the climatic conditions can challenge the structural integrity of buildings. With its flexibility and adaptability, elastomeric liquid is an excellent solution for external wall waterproofing. When applied, it provides an impermeable barrier against water ingress and a smooth finish, facilitating subsequent painting and beautification endeavours.
Access to the external walls of buildings, particularly high-rise structures, can be tricky. Depending on the situation, different access methods are employed. Rope Access, MEWPs (Mobile Elevated Working Platforms), and scaffolding are commonly used to reach and treat these surfaces. Hydro-seal, leveraging its extensive manpower and deep-rooted experience spanning years, is adept at employing any of these methodologies. Their versatile approach ensures that waterproofing applications are executed efficiently, regardless of the access challenges.
Nevertheless, it's imperative to remember that, like all things, waterproofing coatings, too, have a lifespan.
Routine checks and maintenance of the external walls are crucial. Proactive inspections can identify potential problems, allowing for timely interventions. Addressing issues at nascent stages ensures the structure's longevity and obviates the need for extensive and often expensive future repairs.
