INDOOR & ROOF TOP POOLS,
A CONCERN FOR NOISE?
Many indoor and rooftop swimming pools create a noise
nuisance to the neighbours. Usually the airborne noise is
well isolated by the concrete walls and floors, but not the
structure-borne noise. Therefore it is strongly
recommended to apply a CDM POOLS & SPAS isolator
system under the pool, and the surrounding pool deck so
the whole pool becomes floating, with no rigid acoustic
bridges to transmit the structural noise energy. CDM
POOLS & SPAS isolator systems are particularly used to
acoustically float swimming pools, on the roof or inside
buildings.
The base of the swimming pool is the most important
transmission path for the structure-borne noise energy,
and must be isolated appropiately. Essential in the
isolation performance is the resonance frequency, of
the isolation setup. The lower the resonance frequency
the higher the isolation. Please see the CDM system
selector for further information.
Traders Hotel swimming pool, Kuala Lumpur
The walls of the swimming pool are decoupled from the
surrounding structure with the relevant CDM resilient layer
and CDM-ISO-STRIP specified in the system selector.
They are installed in such a way that the walls of the pool
are able to move independently from the structure.
Furthermore the CDM resilient layer wall limits horizontal
movements when the pool is in use and acts as a
formwork, helping reduce the risk of acoustic bridging
during construction of the pool.
Detailing of the other connections from the pool to the
structure of the building, e.g. water drainage systems are
decoupled using resilient (rubber) couplings.
BENEFITS:
- Optimum isolation at minimum system thickness
- Fully tested. Laboratory tested for deflection and creep
- We only use durable materials that are guaranteed to perform over time
- Fast installation
- Full engineering support throughout the whole project

A continuous resilient floor layer on which the frame of
the swimming pool will be installed. No formwork is
required for this system. The floor layer has a wavy
surface to benefit from the optimum shape factor
which results in extra sound reduction.
CDM ISO-MAT 42 and 45
The CDM ISO-MAT is delivered in rolls to minimize
the number of joints and offering a very quick and
easy installation.
Acoustic floor battens with resilient pads. They offer
a minimum contact surface resulting in a higher
acoustic performance than continuous floor layers.
The CDM ISO-LAT is installed under the formwork.
The concrete base of the pool will then be poured on
top of the formwork.
CDM ISO-LAT 82040
The floor battens are very easy to stock, transport and
install.
A pre-fabricated, ready-to-install system that cover the
total surface area of the structural base on which
the floated swimming pool will be built. The system
consists of elastomer pads on a formwork panel with
mineral fibre sound absorption, lateral isolation and a
waterproof polythene membrane.
CDM ISO-FLOAT-CHR 4000/4
The elastomeric pads (fully laboratory tested) can be
changed to accomodate the varying loads of the pool.
Pre-manufactured, bearings able to take large loads on
a small area, typically installed on column heads,
negating the need for a second heavy concrete slab.
The system consists of elastomer pads sandwiched
between galvanised steel or stainless steel plates,
with lateral isolation and a waterproof polythene
membrane.
CDM SWIMMING POOL MOUNTS
The elastomeric pads (fully laboratory tested) can be
changed to accomodate the varying loads of the pool.
