Construction Health And Safety

Why Is Construction Health & Safety So Important?

Health and safety is the most important aspect of any construction project, old or new. Both the contractor and client should always ensure that all aspects of health and safety have been considered before you initiating any construction on site. Health and safety in construction is particularly important because the it is prone to hazardous situations. Working employees on sites have unfortunately succumb to their injuries many times before. Thus, leaving both the contractor and client at risk of receiving hefty fines, being sued or being banned from any further operation.

If you don’t have the correct health and safety procedures in place, you will most likely be breaking the law. If the HSE find that the construction site has not met health and safety regulations, they have the power to act against your business and the client.

Benefits Of Health & Safety

Health and safety is important to avoid injury. However, it also offers other long-term benefits. Thus, by implementing the right health and safety procedures and equipment, your employees are more likely to be happier in their working roles. If your workers have the correct safety harnesses, uniform, equipment and tools, it will boost morale on site and lead to better productivity. Additionally, with less illness and injury you can also gain more productive working hours. Thus, leading to increase in profits. You can build a good reputation for your business and it will help to retain staff.

When Should I Get My Roof Inspected?

Gauteng’s weather is one of the best in the world. With our warm, wind-free summer days and our mild crisp, winters. Never too humid but also never too cold to the point we where we experience below 0 Celsius.

Our heavy rainfall and thunderstorms usually start mid-October. Therefore, we recommend you have your roof inspected between July and September when we are still experiencing dry weather. As roof repair and waterproofing specialists, we experience an influx of job acceptances DURING the rainy season. Which, of course leads to job delays due to the wet conditions. Thus, resulting in frustrated clients as everyone wants their fixed as soon as possible.

Roof Inspections

Roof inspection frequency depends on a number of factors such as; the age of the roof, the condition, latest roof maintenance (if at all), the type of roof system installed, geographical location etc. Roof systems deteriorate for a number of reasons:

  1. Normal wear and tear.
  2. Weather conditions.
  3. Building movement.
  4. Improper design.

Any roof fault will result in damage to the building envelope, interior finishes and loss of occupant productivity. Thus, regular roof inspections lead to early roof leak detection and other early signs of roof system failures.

Tiled Roof Inspections

Since tiled roofs generally experience more leaks than other roof types, we recommend you have your tiled roof inspected twice a year. Tiles and roof ridges are susceptible to cracks, chips and coming loose if not correctly installed. Additionally, valleys are easily blocked by dirt and debris that land on the roof, especially by overhanging trees.

Flat Roof Inspections

General rule of thumb for flat roofs is that they need to be maintained every 2 to 5 years. Depending on the type of waterproofing system you currently have installed. Derbit waterproofing has a torch on waterproofing system that only needs to be maintained every 5 years. Although it is more of an expensive option, it lasts longer than other torch on waterproofing systems. Thus, saving you money in the long run. We recommend you have your flat roof inspected every 2 years. Debris and ponding water cause structural damage when not attended to as soon as possible.

Metal Roof Inspections

Metal roof inspections also depend on a number of it’s own factors; type of slope, penetrations installed (chimneys, whirlybirds, aircons units etc), gutter conditions, overhanging trees etc. Metal roofs are also prone to holes and rust. Therefore, we recommend you have your metal roof inspected once a year.

Our comprehensive roof inspections are free of charge. We have been roof repair and waterproofing specialists since 1992. Contact our professional team today for a free assessment and report.

History Of Waterproofing

A Brief History Of Waterproofing

The history of waterproofing is a very interesting topic. The need to waterproof structures was evident in ancient times. Although there is a little documentation on the subject. The ancient Romans understood the need to waterproof their ground structures by building walls so thick that it was practically impossible for water to penetrate them. In early Egypt, a mixture of clay and straw was used for waterproofing. There were also the first traces of a bitumen and resin mixture found. Also, the ancient Egyptians used asphalt to waterproof the foundations of the pyramids and in other situations on buildings to prevent the penetration of water.

Asphaltum has had many other uses throughout history as well as waterproofing. Containers used for transporting goods were made of a bed of straw or sand. They were then sealed with bitumen on the inside. With bitumen’s inert characteristics it conserved the contents of the containers.

Breakthrough In History Of Waterproofing

Probably one of the biggest breakthroughs in waterproofing was the use of bituminous mastic combined with baked clay.

The Medieval era did not bring any new or innovative products to the waterproofing story. Around the 13th century there was the return of the use of lime for waterproofing. In this period, castles built for the purpose of defending an area either sat on hills or had channels or moats around them filled with water often lined with lead or with a glued asphalt.

Most Famous Waterproofing Project

Possibly the most famous and best-known waterproofing project was that of the Hanging Gardens of Babylon. One of the seven wonders of the ancient world. The Hanging Gardens, comprised of terraces rising over 25 metres from a colonnade superstructure, was commissioned by King Nebuchadnezzar. Additionally, the waterproofing consisted of bitumen and lead.
