Underground drainage inspection can always help you to prevent blockage issues which may cause flooding in the future. Tree roots blockage is one of the common issues which may find easily near the plantation area. Regular inspection is necessary to prevent damage to the underground drainage system.
Here is one example which shows how tree roots can block the stormwater piping system.
Concrete cover is the outer concrete layer serves to protect the rebar in RC structure. Its thickness and density dictates both the protection performance and fire – resisting ability. The extract from the research paper by Albert K.H. Kwan in Department of Civil Engineering, University of Hong Kong , the concrete cover will become much permeability to water once the “water to cement ratio” exceeds 0.4. Adversely does the high water to cement ratio happen in many concreting process in Hong Kong. To account the reason behind , it is the slump of the concrete or the workability of the concrete affects the entire concreting process. The drawback from high permeability is very obvious . The concrete cover becomes lesser defensive against the water nor air penetration . The alkaline environment around the rebar is diminished along with the carbonation due from the air pollution
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.
GBE feels great to the finalised product in SOHO. It is our passion to be Professional in this industry even it was tough life.
GBE was impressed by the character defining element of the historical building. Building conservation consultancy service offers measurement survey to entire building; building element condition survey; structural framing inspection; MEP preliminary evaluation…. too many tasks to enlist.
GBE is called on abroad to offer the in-sight for enhance value of one old commercial complex. This is the time clients need expertise advise to feed all-round explanation, fast and accurate views.
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.
GBE believes an in-depth research is always prior to talk and showoff. There are some urban sites left undeveloped and the entire investment becomes distressed. Professional Survey or PM should be able to draw the attention to the underground land strata which has been resumed by Hong Kong government.
KPDO enjoys much this investment appraisal. With Pro. Surveyor and local Architect , the appraisal empowers much meaningful findings like future layout; market segment; asset “wow” factor; accessibility; historical building site upside; program to turn around …..
GBE gives the relief to stunning structural frame of the premises with careful position the signage going along the row of large glaze window panes wall. Adopt the minor work approach cum design trick for fast turn – round.
