Regular Drainage Piping Inspection for Building


Regular pipe inspection is one of the important preventive maintenance for all buildings. During the coronavirus disease (COVID-19), all residential buildings may experience high usage of water as most of the people have to stay at home for work and daily life. The drainage pipe system may easily get blocked and the aging problem during this period, CCTV inspection can help to monitor the condition of piping system which can find out the potential problems.

The inner coating of the epoxy drainage pipes has been designed to withstand most chemical stress and resist abrasion. Made of an epoxy-resin regularly assessed, this coating benefits from continuous improvement to meet wastewater drainage increasing constraints. Its smooth surface enhances flow capacity and prevents incrustations and deposits. However, the workmanship may affect the piping durability and also create the risk of clogging. Therefore, close monitoring for replacement workmanship is also an important issue to prevent risk.


High Ceiling Inspection

GBE found the relax of headroom from PNAP has posed many difficulties to conduct professional inspection to above high ceiling. We made ourselves accessible with our own rising platform and wifi endoscope. Usually the drainage which poses the hygienic alert is hide above. Our way can ease many people pain.


Stone Cladding Inspection

Whilst stone cladding looks durable, GBE noticed some defects always be down-played its severity.To exemplify here is the hairline crack usually found on the stone surface. It may be easy regard as minor defects but indeed GBE thinks it isn’t.

The anchor bolt is inserted into the stone. The pattern and location of the cracks found near the anchor point becomes an alarming signal for building owners to pay attention to. The crack developed near the anchor obviously weaken the load taking capacity by the bolt. This eventually may cause stability failure.


Know More about Timber Formworks

Timber formworks is the most common for concreting. In general specification of government Edition 2017 GS 2017-02, section 6 emphasizes the formworks requirements. Seldom is discussed the requirement for basic component of formworks and how it affects the construction quality.

The stratum, the propping, falsework, crossing bracing, head tree, purlin/runner and plywood soffit are all critical components to affect the formworks stability, concrete quality, the finishes level and the subsequent follow up works.

Water Seepage Inspection

The water seepage has always been the most panic issue for owners and tenants. The chemical injection has been suggested if the repairing area is limited and no waterproofing membrane can be applied from an exterior wall or above the flooring. After the first chemical injection which the water seepage can happen to other weaken points. Close-up monitoring is necessary for a second or third time. The clients should consider a one-stop solution from inspection to rectification to solve the water seepage issue.
