enerally, the prime concern for concrete for structural engineers has been its resistance to mechanical stress, i.e. strength. In recent years, durability has emerged as equally important. However, durability cannot be achieved with reducing the W/C ratio, high compressive strength, more cement, air-entraining admixtures or corrosion inhibitors alone. To...
Due to the increased importance of quality waterproofing in construction, especially in waterproofing water retaining structures and water excluding structures, there is a lot of misunderstanding and misjudgment about what crystalline waterproofing is (and the various other types of waterproofing that should be applied, depending on the surface) A good...
Concrete corrosion is costing the construction industry and its players millions of Shillings annually in premature repair or replacement of damaged infrastructure. But the new innovations in PENETRON CRYSTALLINE TECHNOLOGY are beginning to allow engineers, architects and contractors to create structures that heal themselves. reinforced concrete pillar corroded corroded...
Leaking basements can present a wide variety of problems. First of all, they have the capability of damaging a building’s structure. They can also pose other serious problems such as mold, bacterial infections and potential damage to electrical lines. Even so, leaking basements become useless...
A unique integral crystalline chemical treatment to waterproof and protect concrete, PENETRON PLUS is specially formulated for dry-shake applications on horizontal concrete surfaces or precast segments where greater impact and abrasion resistance is required. Packaged as a dry powder compound, PENETRON PLUS consists of Portland cement,...
Damaged wall due to environmental attacks Each day concrete and masonry structures are faced with changing environmental conditions, carbon dioxide, chloride attack and other corrosive elements, leaving them vulnerable to damage and deterioration. Concrete and masonry structures undergo destructive reactions due to harsh weather conditions like rain,...
WHAT IS EPDM? EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility....
A roof garden is any garden on the roof of a building or a house. Besides the decorative benefit, roof gardens provide for temperature control, architectural enhancements and recreational opportunities. The main issue is that the time and expense associated with future repairs of membranes to...
In the past year, the Government of Kenya has continued to improve and expand the infrastructure of the country. KNBS reported that the sector grew by 13.6% in 2015 compared to the 13.1% growth the sector posted in 2014 largely due to implementation of mega...
William Foster once said “Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.” The roof, even when not visible, is the most important investment in the building....
