Swimming Pool Renovation using a Vinyl Liner

Renovation of an existing pool using a vinyl liner

The development of vinyl liners has provided the modern pool industry with a method to renovate old concrete pools so that they look exactly like a new pool at an economic cost.

The work involved in a typical renovation of an old concrete pool might be as described below.

In most circumstances a thin factory made liner would be the cheapest and best way to renovate an old pool – but the new Spray Applied Pool Membranes may be more appropriate in certain circumstances.

Concrete Pool Renovation Steps

This approach to the renovation of an existing pool might involve the following:-

  1. Pumping the water out of the existing pool and cleaning the walls and floor for inspection

  2. Cutting a sump at the deep end of the pool that will allow the complete emptying of the pool after ground water entry and/or rainfall

  3. Inspection and repair of any surface defects in the walls or floor

  4. Removal of the existing skimmers and renovation of the tops of the existing walls for connection to a new reinforced concrete slab/ringbeam that will run around the entire perimeter of the pool. This may be required to strengthen the top of the old walls

  5. The installation of new skimmers

  6. The installation of the new steps

  7. The installation of a new main drain, and new water inlets, vacuum point and pool lights.

  8. The excavation of the trenches and installation of new buried flexible pressure pipework between the pool through the wall fittings and the existing pool plant room

  9. The removal of the old pool plant and installation of the new plant in the existing plant room that will provide a full pool water volume change in 6 hours

  10. The construction of the concrete slab / ring beam around the pool perimeter in a 1000 mm wide, 150mm thick mesh reinforced concrete that provides a base for the pool paving and resists ice expansion pressures in the winter.

  11. Re-cleaning of the pool interior surfaces and the glueing of the mineral “carpet” to the walls and floor of the pool

  12. The installation of the liner lock on the top of the new slab / ring beam

  13. The installation of the new thin factory made liner, filling the pool and cutting in the skimmers, inlets, drain and vacuum point

  14. The installation of the coping stones and the paving on top of the slab / ring beam

Liner Renewal Costs

If the pool is generally in good condition and the Work involved is limited to the renewal of gaskets on the skimmmers, drains, submerged lights and water inlets the cost can be as low as £75 per square metre of floor area for a large pool (> 70 m2 ) and £100 per square metre of floor area for a small pool (< 35 m2 )

Renovation Work can be executed by a Local Builder, Plumber and Electrician

All the work described in the Method Statement can be carried out on an Owner-Builder basis by a a Local Builder, Plumber and Electrician - provided that Bluepools oversees the whole process.

This will reduce the cost by at least 50% from the amount that a Pool Installation Contractor would charge.

Costs Depend on Pool Size and Scope of Work

Total renovation costs will depend of course on the size of the pool that is being refurbished and the Scope of the Work involved.

For instance the pool water circulation system may be substandard, the buried pipework leaking, the paving may be very tatty.

Very large pools of 12m x 6m or more may cost about £200 - £250 per square metre for renovation.

The cost increases dramatically for small pools because the overall costs relate to the pool wall length compared with the pool floor area and to costs that do not reduce much for a smaller pool.

Very small pools as small as 8m x 4m may cost as much as £300 per square metre of pool area for renovation.
