As per Endowment requirement the main temple renovation should be done once in twelve years. Earlier one was done in the year 1998 and the previous one as early as 1958. The initial study revealed that major restoration work was expected. The management prepared for something challenging and tough. Appropriate methods, technical expertise and services of varied artisans who have special skills and training were invited to form a expert team.
Renovation of all the Gopuram at the entrance and also inside the temple: There are eight Gopurams including the main Five-storied Gopuram and seven over the sannidhies inside. Estimates have been received from reputed Sthapathies. The best among them is selected.
There are about 40,000 sft of roofing over the mantapams & various sannidhis. These are over the vahana mandapam, yagasalai, Ramanujar Sannidhi, Andal Sannidhi Desikar Sannidhi, Venugopalan Sannidhi, Ramar Sannidhi, Alvar sannidhi, kitchen etc. During heavy rains, profuse leakages were found from these roofings. Since the existing weathering course is ancient, with heavy thickness of layers and liners. many experts were consulted for a suitable solution. Finally a procedure generally as per the following specification was finalised and the initial work has been completed.
ROOF CONDITION BEFORE RESTORATION
LAYER OF KERALA TILES OVER COARSE CONCRETE LAYER.
WEATHER PROOF BITUTHENE LAYER BEING LAID.
While executing the work care was taken to relocate the rain water drains at a higher level for easy flow. The existing slope was not hanged as it was found satisfactory. The structure of old course was not disturbed, considering the legacy of such construction.
There is presently a system to carry part of the rain water into the tank which has been blocked. There are fresh reminders from the Tamil Nadu Government for installation of an effective rain water harvesting system. Since we have two wells within the premises of the temple, it is also required to harvest the rainwater from within the temple area. During heavy rains, the entire water from the roof flows on the prakarams and stagnates due to improper draining systems. Hence an effective system has been designed and executed.
Six wells of four feet diameter and 12 feet depth were first sunk. From the bottom of the each well, slotted pipes of 6” diameter were sunk for further depth of 25 feet. Finally the wells were filled with 2 inches gravel for a depth of nine feet. Then the wells were closed with steel plates.
The complete collection of rain water from the roof tops are directed to these wells by gutters and PVC pipes, embedded below the cut-stone flooring over the prakarams. During recent rain, the harvesting was found to be satisfactory.
There is a structure known as a Neerazhi Mandapam situated in the centre of the tank. This Mantapam is dedicated to Sri Veeraraghava Swamy. The main purpose is to house the deity during the Float Festival.. It is constructed with granite stone.
With the permission and blessings of Srimad Azhagiyasingar, the hereditary trustee of the Devasthanam, the Mantapam went through extensive renovation and cleaning as part of renovation of the Tank and the temple.
On detailed study it was found that the structure had not been repaired. or decades, except for some white washing.
The Neerazhi Mantapam is surrounded by 90 Ft X 90 Ft platform all around. Around 1972-74, at the time of Sri Mukkur Srimad Azhagiyasingar, a tiny tank was dug at the centre of seven acre dry tank, around the Neerazhi mantapam. At that time the dwindling structural strength of the stone structure of the neerazhai mantapam might have been noticed. Due to some restraints, deep study was not made and a 9 inches X 3 feet high brick belt was constructed around the base of the mantapam with the intention of strengthening the structur e. Presently this belt had separated from the stone structure and thick vegetarions have grown which were deeply rooted. Also the stone layer on the mantapam floor was not packed leak proof. Due to battering of weather the water had been seeping into the structure and washing away substantial amount of sandy bottom. This in turn has shaken the foundation of the stone pillars and they started very slowing drifting.
All these are finding of the experts from archeology, L & T and Public Works Department. Under their advice and supervision extensive corrective steps were taken with modern technology and at the same time not spoiling the traditional construction
