Sebastian as us few question :what make you become outstanding among other real estate agent?
what make you deserve 3%
Ground floor basic types
2 basic groups
solid ground floor - supported by ground
floor countinuosly supported by ground
suspended ground floor - spans between support
floor spans between support
example : kampung houses
There are 2 type of ground floor. what is the pros and cons in term of
Floor load
thermal insulation
preventing water and contaminant penetration
durability - water, dampness, soil pollutant, soil chemical composition, soil movements - it will influence the longevity to the floor
why the floor tile pop out in malaysia?
contraction too quickly due to temperature changed too dramastically
aircon switch on during night time . flooring become very cool
Practice that will avoid poping of the tile
1 .movement joint every 8 m - 10 m ( usually did not go beyond 16 m )
and it 5 mm - 10 mm width
2 . soak the tile - avoid sucking the moisture from the cement sand and cement sand will shrink and detached
1.5 mm to 3 mm cement grout - join between tiles
3 . cement sand screeding - in order all the surface of the tile receive even contact of cement equally
Trick : Ask the tile supplier teach the worker or educate them how to do proper tiling or if pop out then blame the supplier
Surface finish
smooth and leveled surface finish to allow floor covering
ground floor provided the structural floor level - sff
finished floor level - ffl is the finished level to be used above screed. normally its higher than sff
DPM -
DPC -
Hardcore
Blinding
Ground supported or solid floors
Door sill or threshold
conduct rain water away from door to a drainage system providing disabled access :
wheel chair access
eliminate any difference of level between outer paving and internal floor - max 10 mm
suspended ( hollow ) floor
cement
timber
due to hyroscopic nature of timber - adsorbs water from humd air need to prevenet moisture related deterioration using
- ventilated below floor void - air brick ventilation
- prevent contract with external wall - floor joists supported on sleeper walls
- cross ventilation of void - sleeper walls built in honeycomb bond with hollows
suspended beam and block ground floor
sound insulation
fire safety
resistance to passage of heat
achive ffl requirement
reinforeced concrete advantages
better resistance to damage to fire
safely supports greater load
easily accessible
cheaper
timber floor advantages
