What is the meaning of ‘Modern Methods of Construction’
The use of innovative and off-site manufacturing techniques to construct buildings. e.g. precast panels and foundations.
What is the meaning of ‘traditional’ methods of construction?
Traditional methods of construction relate to on site building processes.
What are the benefits of modern methods of construction?
Cost effective.
Sustainable.
Precise.
Reduced waste.
Better quality control.
Allows for streamlined construction.
What are the benefits of traditional methods of construction?
Allows for more flexibility for onsite changes.
What are the drawbacks of traditional construction methods?
Traditional construction relys on onsite labour and materials which can often lead to inefficiencies and delays.
It is also suceptible to weather conditions and inconsistencies in quality.
What is a septic tank?
A septic tank is a buried, watertight container that holds wastewater and partially treats it.
A septic tank has two main elements.
1. The underground tank.
2. A drainage field.
How does a septic tank work?
The raw sewage flows into the tank where it then seperates into three layers; scum, sludge and effluent.
The effluent is the liquid wastewater which exits the tank and travels into the drainfield for further treatment.
The drainfield is a shallow excavation in unsaturated soil that allows the wastewater to filter through the soil and disperse into groundwater.
For the rural house in chorleywood, which septic tank did you use and why?
As the property was a 6 bedroom house, it required a 4000 litre septic tank, and one from the Klargester brand was chosen.
